Thermally Activated Dislocation Motion in FCC and Refractory BCC Metals

Description: Amplitude-dependent internal friction evidence is presented which demonstrates the strong differences in dislocation mobility which exist between the two classes of cubic metals: the face-centered cubic, represented by Al and Cu, and the body-centered cubic, represented by Ta, Nb, Mo, and W. Amplitude- dependent internal friction due to dislocation motion results from the hysteretic unpinning and repinning of dislocation loops from impurity pinning points when the oscillating measuring stress e… more
